SiE'ECIFIGATION forming part of Letters Patent No. 537,99 9, dated April23, 1895.

' Application filed December 27,1894. Serial No. 533,135- (No model.)

; sled in which the runners are adapted to readily pass over anyobstacle encountered, each of said runners being also independent of theother so that when one runner passes over an obstruction the otherrunnerwill be unaffected.

A further object is to provide a sled with an improved construction ofknee and rave whereby great strength is obtained and whereby the runnersare connected with the supporting axle for the purpose of attaining thebefore described object; and my invention consists in the novelconstruction, arrangement and combination of parts ashereinafterdescribed, illustrated in the drawings and pointed out in the claims.

In the drawings, Figure 1 is a plan view of my improved bob-sled. Fig. 2is a transverse sectional view taken through the center of thesupporting axle. Fig. 3 is a side elevation. Fig. 4 isa perspective Viewof the knee and rave detached.

1 indicates the runners of the sled, the same being formed in the angleor L shape shown and pivotally connected at their forward ends with theopposite ends of a connecting rod 2. To the said rod is secured thetongue or pole 3. L

4 indicates the improved knees, the same comprising the diverging arms 5and the connecting piece 6 integral with said arms. The lower ends ofthe arms are bent horizontally and are bolted to the horizontal portionsof the runners. To'the upper face of the portions 6 of the knees arebolted the diverging arms 7 of raves 8, which are perforated as at 9,and have the integral inclined arms 10, which terminate at their lowerends in broadened feet or bases 11 which are bolted to the horizontalportions of the runners. Each of the pieces 6 of the knees is perforatedas at 12 in alignment horizontally with the perforations 9.

13 indicates the supporting axle or shaft which passes loosely throughthe perforations 9 and 12, thus pivotally supporting the runners fromsaid axle. The axle is provided centrally with a plate or disk let towhich is pivotally connected the bolster 15 by a pivot stud or bolt 16.

It will be seen that by reason of the runners being pivotally connectedin an independent manner with the axle, when one of said runners meetswith an obstruction, the remaining runner will not be affected, and itwill also be seen that the construction and arrangement of the knees andraves gives great strength to the device.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is i 1. In a bob-sled, the combination withthe runners of the knees having diverging arms bolted to the runners andintegral connecting pieces, the raveshaving diverging arms bolted to thesaid connecting pieces and with inclined arms bolted at the lower endsto the runners,and an axle passing loosely through openings in the ravesand knees,in the manner and for the purpose set forth.

2. In a bob-sled, the combination with the runners of the knees havingdiverging arms and the horizontal integral connecting pieces, the raveshaving horizontal diverging arms bolted to the upper face of saidconnecting pieces, and also having integral inclined arms bolted to therunners, an axle passingloosely through openings in the raves and thehorizontal portions of the knees and a connecting rod to which the frontends of the runners are pivotally connected.
